The Sacrament of Reconciliation is available before or after Divine Liturgy and also upon request. If priest is not in the confessional, please try to find him and notify that you want to go to confession. Otherwise sit and wait in the pew that is next to the confessional.
You may request Holy Sacrament of Confession by sending email to firstname.lastname@example.org or calling to the church office 770-760-1111.
Also you may book time for confession or spiritual meeting using Calendly. But in this case, you should receive confirmation email that this time is still available.
